1020-31-1 SEMI-HINDERED PHENOLS. 1. SYNTHESIS OF 3,5-DI-TERT-BUTYLSALICYLIC ALDEHYDE

 https://www.lookchem.com/CASDataBase_1020-31-1.htm

Some differences were observed in the solid- and liquid-phase benzylic oxidation of 2-(hydroxy- or dialkylamino)methyl-4,6-di-tert-butylphenols.Oxidation of these semi-hindered phenols with lead tetraacetate gave a new compound: 3,5-di-tert-butyl-ortho-benzoquinone diacylal.Keywords: semi-hindered phenols, synthesis, aldehyde, benzylic alcohol, oxidation, liquid phase, solid phase.
